Obtaining a Social Security Number

You are here

The purpose of a social security number is to be able to pay taxes in the U.S. Although the number is often used for identification purposes, the social security administration will only issue a number to an F1 international student if you are legally working in the U.S. or have a concrete job offer. If you work while in the United States, you'll need to pay income tax. The social security number is how you'll be registered with the U.S. government to pay that tax. As an F1 student, you will probably not need to pay the "social security" or FICA tax, but you will need a social security number to pay the other mandatory taxes.

Do I need a Social Security Number?

Social security numbers are required for:

Employment: You must have a social security number in order to work in the United States. You may apply for on-campus employment, or later for OPT or CPT off-campus. See your international student advisor for details.

Social security numbers are not required for:

Driver License: If you are not eligible for a social security number, you may get a letter from your local Social Security Administration office stating that you have never been issued a number and bring this letter to your local Motor Vehicle office, along with your passport (including your US visa and I-94 card) and your I-20, where you can apply for a driver license. If you plan to have a car, you should take the driving exam and get a Colorado Driver License.

Class Registration: It is not necessary to have a social security number in order to register for classes. International students use an nine-digit number called Red Rocks International Student ID number to register for classes. The International Student Services & Programs office will assign one to you.

Banking: Although some banks will ask you for it, F1 visa holders do not need a Social Security number to open a bank account. The bank may ask F1 visa holders to fill out Internal Revenue Service form W-8 to prove that they are exempt from the requirement of providing a social security number.
